I will pump 4hrsly w/out fail, even to wake up in wee hours to pump (still do so when I'm back to work) My breast can only tahan 4hrs outside so no matter what, I have to reach home to pump else, I will engorge till very pain or worst, I will suffer from blocked ducts (which happened to me many times).
If I need to go out at 12pm, I will pump at 1130am and I need to reach home by 330pm for pumping again. During that 'criticle' period of breastfeeding, very seldom I will go out for too long coz it will affect my supply.
When Inez turned 5mths, I start to prolong the pumping hours from every 4hrsly to 6hrsly..
Now and today Inez is 6mths old, I've 'trained' my breast to pump 3 times a day which is 730am, 430pm and 1130pm so I could stay outside for 8hrs.
